DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: an anti-wrinkle device in film processing and winding, comprising: a substrate support frame 1, support legs are fixed at the corner positions of the bottom end of the substrate support frame 1, support frames 3 are fixed at both ends of one side of the top of the substrate support frame 1, and a support frame body 5 is fixed on the side of the top of the substrate support frame 1 away from the support frame 3.

[0024] See also Figure 1-4, an anti-wrinkle device in film processing and winding, comprising an anti-wrinkle component 2, which is arranged at the top of a substrate support frame 1, and comprises a first tensioning roller rod 22 and a second U-shaped frame 23, through which the film is rolled and wrinkle-proof. The anti-wrinkle component 2 comprises a rectangular slide 28 opened at the top of the substrate support frame 1, and a tensioning bracket 25 fixed to the top of a square-shaped frame 21, wherein the lowest end of the square-shaped frame 21 is higher than the lowest end of the bottom support leg of the substrate support frame 1; the square-shaped frame 21 and the tensioning bracket 25 slide on the top of the substrate support frame 1 through the rectangular slide 28, the second U-shaped frame 23 is located in the tensioning bracket 25, and the first tensioning roller rod 22 rotates in the tensioning bracket 25 and the second U-shaped frame 23. The anti-wrinkle component 2 also comprises a threaded adjustment rod 24 threadedly connected to the tensioning bracket 25, and the bottom end of the threaded adjustment rod 24 is rotatably connected to the top of the second U-shaped frame 23. The threaded adjustment rod 24 and the second U-shaped frame 23 are T-shaped rotationally connected; wherein a cross-shaped rotating handle is fixed to the top of the threaded adjustment rod 24; the anti-wrinkle component 2 also includes a vertical fixing plate 29 fixed to the bottom of the substrate support frame 1 close to the side of the support frame body 5, a T-shaped guide rod 27 passing through the vertical fixing plate 29 and a first spring body 26 sleeved on the outer wall of one side of the T-shaped guide rod 27, and the T-shaped guide rod 27 is fixedly connected to the U-shaped frame 21. The film passes through the middle of the upper and lower first tensioning rollers 22, and the threaded adjustment rod 24 is manually rotated. During the rotation process, the threaded adjustment rod 24 will adjust the height of the second U-shaped frame 23 according to the condition of the film. At this time, the upper and lower first tensioning rollers 22 squeeze the film, and then drive the film to move during the rotation of the film winding drum, and then drive the first tensioning roller 22 to rotate, thereby smoothing the film. At the same time, when the winding drum increases, the tensioning bracket 25 moves smoothly along the rectangular slide groove 28. At this time, the U-shaped frame 21 and the vertical fixed plate 29 guide the tensioning bracket 25 to ensure that the tensioning bracket 25 moves smoothly on the substrate support frame 1. Since the tensioning bracket 25 is affected by the first spring body 26, it can tension the film when the film winding drum winds it.

[0025] See also Figure 1 and Figure 5, an anti-wrinkle device in film processing and winding, further comprising a tensioning assembly 4, the tensioning assembly 4 being arranged at the top of the substrate support frame 1 and located inside the support frame body 5, and the tensioning assembly 4 being used to tension the film. The tensioning assembly 4 comprises a second spring body 43 fixed to the bottom end of the substrate support frame 1 and the top end of the support frame body 5, and a telescopic rod 44 assembled in the second spring body 43, and the second spring body 43 forms a reset structure through the telescopic rod 44. The tensioning assembly 4 also comprises a second tensioning roller rod 42 fixed to the other end of the second spring body 43, and a second tensioning roller rod 42 rotating in a first U-shaped frame 41. When the film is wound on the second tensioning roller rod 42, the first U-shaped frame 41 moves up and down in coordination with the second spring body 43 through the telescopic rod 44, thereby adjusting the position of the second tensioning roller rod 42, and tensioning the film through the upper and lower second tensioning roller rods 42, thereby playing a partial anti-wrinkle role during the tensioning process.

[0026] Working principle: first, wrap the film around the second tensioning roller rod 42, and at the same time, pass the film around the upper and lower first tensioning roller rods 22, manually rotate the threaded adjustment rod 24, and the threaded adjustment rod 24 rotates and moves up and down on the tensioning bracket 25. At this time, the first tensioning roller rod 22 on the second U-shaped frame 23 squeezes the film, and then when the film winding device on the supporting frame 3 winds the film, when the diameter of the film winding drum increases, the film drum squeezes the tensioning bracket 25. At this time, the first spring body 26 is compressed, and the tensioning bracket 25 is away from the supporting frame 3. However, through this structure, the film can be tensioned during the winding process, keeping the film winding drum more compact.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
